"Toi prevent the screens13 and 14 from whipping'su 'd breaking under the'vib'ratory action of the screen structure, afpluralityof H spacer rods o'r pipes 15 extend between the side walls 12 and are arranged at suitableintervals-between the upper and'lowerends of the screens 13 and 14 and slightly above'the 'n'ormal plane thereofso that the screen cloth f is drawn tightly thereover somewhat as' "shownin-Fig; 4 and the spacer rods orpipes f 3015 thus prevent whipping andfbreaking of thescreen'cloth which would otherwise occur.- Mounted on the frame" l'above thescreens' 13 and14, is a' compartment 21 having end walls 22 and '23, side walls24and a top wall onto the upper screen 14.7 A rotary member '27, which' may be vinrthe form of a brush or i fotlierwi'se, depending upon the material to be operatedupomis mounted at the front of the compartment 21 so as to project under the f-wall 23, said brush being of sub'stan tiallythe same'length as the widthbetween the side i walls 24 of thecompartment, and thisrotary member isarranged and operated in the proper dir'ectionindicated by the arrow in Fig; l so; as to sweep material from the hopper J '9' into the compartment 21 so that, the matefri'al'is" not'only broken up into particles by ""th eoperation. of the rotary member, but is,

thrown about in the compartment and aerated i bythe' spraying or distributing action of the frotaryme'mber 27. i i I s The fside walls 24'of the compart1nent21 j "extendjforwardly along the ends of the brush 5 27 to thehopper so'as toform a passageway therebetween and the bottomof this passagej way consistsof a plate orcarrier member 29 which'is hingedly mounted on 'ashaft 30 so 'ja's to swing to and from the brushm'ember 27.

I Said plat'e 29 is held in adjustable relation to the brush 27', by an arm 31 rigidly'secured to 1 the shaft'30 andhaving a link 32 on the outer end gezitending loosely through abracket 33', which secured to the sidewall 6 of the ssj'ma ingsaid link 32. being provided with a nected by the belt 41 with a drive pulley of a tween similar bars 50, which,fl.howe.ver,'fare M driving pulleyof-the motor 40 so that the compartment 21 and finally deposited'on the,

is connectedat its upper end of the shaft f '62 and at its lowerendt'o anjadjusting bolt spring 42 thereon'which is compressed be tween the bracket 33 and a wingnut 43 to exert a lifting tension on the arm, 31 and hold motor 140 which, is mounted on the frame of the machine under the inclined screen frame.

' The shaft 28 of the brush27 also has a pulley 38 thereon which is driven by the belt39 from brush 27 is rotated as the auxiliary screen frame is vibrated,

In the operation' of the machine,"the mateput'intoflthe hopper 9 and the "motor'40 is started. The material falling upon the plate 2 9will be swept into' the compartment 21, being at the same time pulverized by'the action: of the brush 27, thrown about in the screen'14. "The rotation of the shaft 35 car-' rying the'eccentridwe'ights -36,".ca'uses the 3 screen frame to oscillate and vibrate and a rapid and efiicient sifting" action willresult. The coarse material not going'thro'ugh' the screens 14 and 13, willbe'disposed 'of through "chutes 17 and 16respectively and the finer material will be dropped out through-the Referring now to the structure shown in 1 Figs. 6 to 9 inclusive,the machine isfsubstantially the same as-that previously'described except tha ta vibratory chute isfsubstituted in place of thehopper 9, brush 27. and resilientbottom plate 29. In this modi 10 fied structure, the top or cover 54 of the ma chine is elevated somewhat at the forward end to accommodate a chute 55 through v which material is delivered to thezupper end of the vibratory screen frame, said chute beinghresiliently mounted and connected with the vibratory screen frame to have a-vibratorymovement imparted thereto: To this end, the forward'end of the chute'55 is proi vided with a pair ofibolts 56 which pass.

downwardly through apertures in a cross member 57 and each boltis provided'with springs 58 and 59 above andpbelow the mem- The lower end of the chute 55 has across endwith a rubber ball 63 and ea'ch ball rests on the outturned flange of a bracket64on the A spring 66 whicheng'ages through an aperture of frame for holding the rubber the bracket plate 64.

The screen frame 70 of thestructure of Figs. 6 to 9 inclusive, is the same as and ball 63 against 1L6 vibrated in the same manner as the screen structure of the precedmgfigures and the vibratory movement of the screen frame is transmitted to the chute 55. To prevent spilling the material as it is being supplied the open top compartment upwardly'in the open bottom compartment, and an inclined screen resiliently mounted on the frame in m to the chute '55, a cover member 68 is proi vided having side walls 69 whicn extend down close to the sides of the chute 55. 1

While I have shown and described my invention in a preferred form, I am aware that various changes and modlficatlons may be made without departing from the principles of my invention, the scope of which is to be determined by the appendedclaims.

I claim as my invention:
